Thanks to all for your insight. much appreciated.
I've just started collecting stamps and have just six left to get then I'll have from 141-638, coils are in pairs.
I'm going to skip the Admiral lathework for now
I ask this question because the value now is becoming more expensive, especially for the MNH stamps.
I don't want to be buying regummed stamps.
The stamp in the OP is a #165 so of minimal value.
I first thought the glue looked normal except for the top portion then I noticed the perf's didn't seem to have any whiteness on the tips from where they were separated.
The stamps not mine so I can't supply any more info other then what's in the photo.
Sorry, It's probably nothing it's just I've never seen a regummed stamp in hand.
